Bring Precision To The Woodshop With An Electronic Router Lift


1 of the knocks that woodworkers get from the metalworking crowd is that their chosen substance is a bit… compliant. Measurements only want to be in just a 1/16th of an inch or so, or about a millimeter, based on which facet of the Atlantic you’re on. And if you are off a little bit? No concerns, which is what sandpaper is for.

This digital router raise is supposed to near the precision hole and make woodworking a little bit a lot less subjective. [GavinL]’s develop guidance are obviously aimed at woodworkers who have not dabbled in the earth of Arduinos and stepper motors, and he does an admirable work of addressing the hesitancy this group could feel when tackling this kind of a construct. The good news is, a ton of the mechanical facet of this venture can be resolved with a commercially readily available router raise, which attaches to a desk-mounted plunge router and allows wonderful adjustment of the chopping tool’s height from above the table.

What is still left is to add a NEMA 23 stepper to drive the router elevate, in addition an Arduino to regulate it. [GavinL] arrived up with some nice features, like a immediate jog management, a fine adjustment encoder, and the capacity to deliver the instrument all the way up or all the way down rapidly. A different really nice touch is the speak to sensor, which is a pair of magnetic probes that attach temporarily to the instrument and a top gauge to point out contact-off. Look at the movie below to see it all in motion.

Just one quibble we have with [GavinL]’s setup is the quantity of dust that the stepper will be subjected to. He may well want to switch out to a dustproof stepper faster alternatively than later. Even so, we think he did a great work bridging the gap between mechatronics and woodworking — a thing that [Matthias Wandel] has been executing excellent work on, also.
